o alli whom it may concern I Be it inrcwn that I, ABBA VAN Wennen, a cof the United States, and a resident of ort Wayne, in the Acoux'rty'ofAllen and r'ltate of indiana, have invented certain new i, to theaccompanying drawings, Vand to the rs of -reference marked thereon,which 1 t part of this specification.

his invention relates `to improvements in stop n'ieohanism for Wringersand the like and 'conf-)ists of the matters hereinafter described andmore particularly pointed out in the appended claims.

The invention herein is shown as applied te a wringer used on a Washingmachinecf a well known type comprising a tub with a hinged iid forholding the clothes and water and a beater or dolly mounted on a shaftdepending from the lid into the tub f adapted to be given a rotary,oscillatory ement. The gearing for operating the v terms no part yof thepresent invent-ion, the une being described and claimed in pi entgranted to me on the 10th day of 1912, Number 1,038,239. The

- Av iger is of familiar type and is attached to 'the fined to of thetub at one side of the hinged lid and the operating mechanism is ca wieof driving the operating shaft of .wid wringer continuously in eitherdirec the parts shown in Fig. 2, in a plane indi.

cated by the line +4 of Fig. 2. Fig. 5 is avievv representing the wringand the rc mechanism in side e ovation and partially in verticalsection. Fig. 6 is a view representing a vertical section through Fig. f'in piane indicated by the line- 6-6 'of Referring 'now to thatembodiment of my ,invention illustrated in the drawings, 10 indicates aWashing machine tub` of familiar construct-ion having a hinged iid 11, afixed top part 1'2 to which the lid is hinged and a fixed top part 13located at one Aside of the hinged lid and extending at right angles tothe fixed part 12. Said fixed part 13 is adapted for the attachment of awringer 14.

15 indicates an operating shaft 'extending in 'a direction at rightangles to the vertical plane of the wringer 14 and adapted to be driven,as shown in the drawings, by a large gear 16 which meshes with thepinion 17 on the hub 'of a large lyiwheel or pulley 18 that is powerdriven. The outer end of the shaft 15 has hearing 'in an upright arm 19rising from a bearing plate 2() attached to the side of the tub.

21 indicates 'a second operating shaft extending parallel to theoperating shaft 15 and adapted through a segmental gear 22 to impart arotary oscillatory movement to a beveled pinion 23 which is fixed to thetop of the dolly shaft. The connections between the gear 16 and theshaft 21 are such as t0 change the continuous rotary movement of thegear 16 into a rotary oscillatory movement of the operating shaft 21. Inthe particular construction of gearing illustrated, means is alsoprovided, as in the construction described in the application referredto, for actuating the gearing by hand power if desired.

As before pointed out the part of the mechanism for operating the dollyshaft forms no part of my present'invention as claimed herein and thefurther description thereof will be unnecessary.

24, 25 indicate the rolls of the Wringer 14. One of said rolls, as shownin thedrawings, the lower roll 24, has a shaft 26 which Ais prolongedbeyond the wringer frame and has bearing in a casing 27 located at therear end cf the Wringer frame and attached to the wringer board 13.

T28 indicates a gear fixed on the yshaft 26 and in mesh with 'a gear 29mounted on a horizontally extending stud made rigid with the wall of thecasing 27. Said gear 29, as shown in the drawings, is made integral witha bevel Agear 30, placed in an adjacent plane in front of it landadapted for engage ment; with 'either one of two beveled pinions ,31, 32that are fixed on a shaft 33 and cen-- shaft 15, said sleeve havingbeyond the shaftV 15A diametrically opposite longitudinally eX- tendingslots 37, 37. The end of the shaft 33 slidingly engages within thesleeve 36 and is provided with a pin 33, the projecting ends of whichengage in said slots 37, 37, so as to prevent a relative rotationbetween the shaft 15 andthe shaft 33 while at the same time permitting alongitudinal movement of the shaft 33 with reference to the shaft l5.

0n the shaft 33 intermediate the beveled gears 31, 32. is mounted asleeve 38 in which said shaft has rotative bearing. The sleeve is heldfrom endm'se movement on the shaft by reason of 'the engagement of itsends against the reversing gears V31, 32. Said sleeve 38 has a verticalflat face 39 on its side toward the end of` the wringer and is Drovidedwith a projecting pin 40 which enorages within a vertical slot 41 in arock-arm 2 that is keyed to the end of a shaft 43. Said shaft 43 islocated below and extends parallel to the wringer shaft 26. lt projectsat each end beyond the wringer frame where it has bearing in uprightplates 44, 45 that are located adjacent to the ends of the wringer frameand are the wringer frame and to the wringer board thereby producing avery rigid construction. lt is apparent that by rocking the shaft 43endwise movement may be imparted to the shaft carrying the beveledreversing gears 31, so as to bring either of said gears into mesh withthe idle pinion 30 and thus produce a rotation of said pinion and withit the wringer roll in either direction. When the rock-arm 42 is in itsintermediate position neither of the gears 31, 32 will be in mesh withsaid idle gear 30 and the Wringer rolls will remain at rest. v l

At, the frogit end of the wringer there is secured to the rock-shaft 43adjacent the upright. bearing plate 45, a roclnarm 46.

47 indicates a swinging controlling lever which is located in a planeintermediate the bearing plate 45 and the rock-arm 4G is fulcrumed inany convenient manner on vsaid bearing plate 45. The fulcrum of saidlever 47 is located below the top of the rock-arm 46 which is providedwith a radially extending slot 48 in which engages a pin 49 carried bythe lever 47. The lever 47 has a crank-handle 50 for convenience inoperating it. it is apparent that by swinging the lever 47 in eitherdirection, the engagepreferably bolted both toy ment of its pin 49 inthe slot 48 of the crankarm 46 will cause said crank-arm 46 to be swungto the .left or to the right according to and corresponding to thedirection in 4which the lever 47 is swung. Thus by 70 swinging the lever47 either of the revers ing gears maybe brought into mes-li with theidle ear 30. In the intermediate vertical position of said lever, thereversing gears will be in an inoperative position.

ln order to lock the rcckarm 46 in posiw tion when either of thereversing gears are in. engagement with the idle gear 30, the followingconstruction is provided: 51, 52 indicate stops located at each side ofand below 8G the level of the fulcrum of the Controlling lever 47. Saidstops are preferably made adjustable in a vertical direction and areadapted to limit the swinging movement of the lever 47 in eitherdirection. As shown, said stops are. in the form of set-screws which arethreaded through ol'sets 53, on the upright bearing plate 45. Byadjusting said screws the lever 47 is stopped in that positioninWhichthe gears have been brought M into proper mesh, and the parts areso proportioned relativeto the total endwise Inoveme'nt of the reversinggears in moving from operative position to the other that the pin 49will pass below. the level of the fulcruin 95 of the lever 47. Thus anytendency to ro tate the rock-shaft 43 and the roclrarrn 46 to disengagethe reversing gears will be resisted Since such rotation would acttorotate the pin 49 through the lower shorter are 1G, of a circledescribed about the said fulcrnm and this is resisted by the s/tops 51,52. ln other words, the pin 49 is caused vto pass below the dead centerwhen the reversing gears are brought to operative engagement and the10,5 lever arm is held in position until force is used to raise saidleiter sutiiciently for said pin to pass above said position. Suchconstruction is simple and ed'ective for the purpose intended and doesaway with theJnecesn@ sity for spring dogs or catchers to retain thecontrolling lever in operative position.

The operation of the reversing mechanism will be readily apparent fromthe above descriptionf In order. to provide for a quick and as nearly asmay be automatic release in case the ingers should be caughtA betweenthe rolls of the wringer, l providethe following mechanism: The bearingplates 45, 44 2Q are extended upwardly beyond the level of the topwringer roll, as clearly shown in Fig. 5 and are there provided withbearings 'for a horizontal rock-shaft 54 located in the vertical planeof the ivringer. t g5 each side of the top wringer roll and on a levelslightly above the horizontal plane containing the line of contact ofthe ivringer rolls are located horizontal bars 55, 55, which aresuspended by links 56 from crossn y 30 mula 'finiiwn with Onpofiteiyrotative ',U'Fd to be Opnrated in either fin@ for :initiating Sai-'idementi fng genre. im idle efir nggfigvd by one nr the ot -er gj gezins.sind i w wni x r in 75 v tion trmn nn iizffi'erfuive in #2 inninepmiiion in un Opel tive pmtition`r mmfng member fur moving said nonifitniing n'iei'nber, yieiding means @it the nififement 0i" sind con nier from its inopratuin, nimm@ fOr lockimex'atiive position. triggers Aessi; #wie of saisi eeinmis, and fwvlmn 1 ii fei'iaedintt said lritrgermem i und inviting means for ieinasing :Viiv fieking' ,ux-ans wheneirher of said trigger :Heimwerk i Struck.
